Existing electric wire is mainly the metal wires such as copper, aluminium as conductive core in the market, and rubber, plastics lead to as clad Cross co-extrusion modling and be processed as conductor wire, elongation at break is usually no more than 15%, because high-frequency irregular folding, winding and Strength stretch etc. reasons, electric wire fracture lead to not using thing frequent occurrence.Meanwhile the coating layer material of current electric wire exists Need tens of even more than one thousand years that could degrade in natural environment.Conductor wire leads to not because updating or damaging using then direct Become electronic waste, bad influence is generated to human body and environment.
To extend the efficient active time of conductor wire, alleviates the status in electronic waste besieged city, need a kind of biodegradable Flexible wire not only solves electric wire phenomenon of rupture caused by existing conductor wire folds because of high-frequency, winds, strongly stretches, but also Also avoid the harm caused by human body and environment of discarded conducting wire.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provide it is a kind of have both environmental protection and it is easy to use can The preparation method of biodegradable flexible conductive wire.
The present invention is achieved by the following technical solutions:
A kind of preparation method of biodegradable flexible conductive electrical leads, comprises the following specific steps that:
(1) mixture of the pure and mild small molecule dihydric alcohol of polyester binary is dehydrated 2-2.5 under certain vacuum degree at 120-125 DEG C Hour, so that for water content 0.05% hereinafter, being cooled to 60-65 DEG C, discharging is spare in mixture, it is soft segment part A；
(2) using diisocyanate as hardness part B, A, B is mixed according to certain molar ratio, then heated while stirring To 100-110 DEG C, biodegradable flexible polyurethane resin matrix is prepared；
(3) by mass, 0.2-10 parts of conductive functional filler, 100 parts of biodegradable polyurethane resin matrix, 0.3-1 are taken The coupling agent of part, which is mixed evenly, prepares biodegradable flexible polyurethane resinous electricity wire inner core；
It (4) is cladding insulating layer with biodegradable flexible polyurethane resin matrix, with biodegradable flexible polyurethane resin Electric lead inner core is internal layer, is sent into extruder by being coextruded up to electric lead of the present invention.
A kind of preparation method of biodegradable flexible conductive electrical leads, polyester diol described in step (1) are that molecular weight exists Polycaprolactone diols (PCL), polyethylene glycol adipate (PEA) between 1000-4000, polybutyleneadipate refer to One or both of (PBA), small molecule dihydric alcohol is 1,4 butanediols, one of hexylene glycol, ethylene glycol.
A kind of preparation method of biodegradable flexible conductive electrical leads, certain vacuum degree described in step (1) refer to- Under the vacuum condition of 0.97Mpa.
A kind of preparation method of biodegradable flexible conductive electrical leads, diisocyanate described in step (2) are that toluene two is different Cyanate (TDI), methyl diphenylene diisocyanate (MDI), isophorone diisocyanate (IPDI), two isocyanide of hexa-methylene Acid esters (HDI), dicyclohexyl methyl hydride diisocyanate (HMDI), naphthalene diisocyanate (NDI), two isocyanide of polymethylene polyphenyl One of acid esters (PM200) and paraphenylene diisocyanate (PPDI).
A kind of preparation method of biodegradable flexible conductive electrical leads, by A, B according to certain molar ratio described in step (2) It is mixed, refers to and mixed according to the molar ratio of 1:1.05.
A kind of preparation method of biodegradable flexible conductive electrical leads, conductive functional filler described in step (3) be electrically conductive graphite, One or more of graphene, carbon nanotube, quaternary ammonium salt ionic liquid, nano metal particles, nano metal fiber mixture.
A kind of preparation method of biodegradable flexible conductive electrical leads, coupling agent described in step (3) are as follows: γ-glycidol Ether oxygen propyl trimethoxy silicane (KH560), amido functional group silane (KH550) and γ-methacryloxypropyl front three One of oxysilane (KH570).
The invention has the advantages that
(1) a kind of biodegradable flexible conductive wire provided by the invention has preparation process simple, environmentally protective, and raw material come The features such as source is extensive.
(2) present invention uses biodegradable flexible polyurethane as conducting wire substrate, and there is excellent elongation at break to be Conducting wire under high-frequency irregular folding, winding and strength pulled out condition have good electric conductivity, extend the clothes of conductor wire Use as a servant the time.
(3) biodegradable soft polyurethane matrix used in conductor wire prepared by the present invention has good biodegrade Performance, it is ensured that because update caused by conductor wire waste it is biodegradable in the natural environment, electronics rubbish can be greatly reduced Harm of the rubbish to human body and environment.
